TEAT CUP.

Application led February 25, 1920. Serial No. 361,116.

To all 'whom t may concerne.'

Be it known thatA we, CLYDn @DEN and HENRY vR. MOORE, of i Syracuse in the county of Onondaga, inthe State of New York, have invented new and useful Improvements in Teat Cups, of which the following, taken in connection with the accom` panying drawings, is a full, clear, and exact description.

This invention relates to certain improvement-sin teat cups for milking machines.

Broadly, the object ofthe invention is to f? produce a teat cup which is simple, strong and durable in construction, efficient in operation, and capable of being readily assembled for use, or takenv apartfor cleaning or repairing. v Specific objects relate to the details of construction of the teat cup, as will more fullyv appear from the following description, `taken in connection with the accompanying drawings, in which j Figure 1 is an elevation of the teat cup.

Figure 2is a vertical section through the same.

Figure 3 isan elevation of the clamping mouth piece.

Figure l is a vertical sectionV through the clamping ring.

The teat cup as shown, comprises a casing 1 a flexible, collapsible tube or inflation 2 a nipple 3 which may-be of glass, metal or other suitable material, and a clamping ring 4 externally threaded for adjustable connection to the threaded lower end of casing 1 for securing the nipple 3 and lower end of the flexible lining 2- in proper position.

The feature of our present invention resides specically in the combination with the upper cylindrical portion of the casing, of a peculiarly shaped and formed clamping mouth piece, designed to properly define the opening into the inflation, and at the same time acting to positively secure the upper end of the flexible lining or inflation in position relative to the casing.

For this purpose the clamping mouth piece 5 is of tubular form, substantially circular in cross section, and having upon its exterior surface a plurality, in this instance two substantially parallel circumferential grooves or channels 6 and Thegroove G is defined by a pair of outwardly projecting4 flanges 8- and 9 of substantially equal radii soas to form a substantially symmetrical groove. rlhe lower wall of flange 9 is inclined downwardly at ten (10) to constitute the upper wall of the groove 7 and the base 11 of said groove may, if desired, be substantially fiat. The lower wall 12 of the groove 7 ,is formed by a flange 13 projecting outwardly from the body of the clamping ring, a distance somewhat less than the projection of the anges 8 and 9 In other words, the radius of the circle defined by flange 13 is somewhat less than the radius of the circle deter` mined by the outer surface of flange 9 The mouth piece 5 is preferably formed with a downwardly tapered wall 14 extending some distance from flange 13 to permit the insertion of the said mouth piece within the inflation 2- with little or no difficulty. j

The upper end of the casing 1 is not flared outwardly in the usual manner of manufacturing lthis type of teat cup, but is of substantially uniform diameter throughout. v n 4 In operation, the flexible lining Q when withdrawn, or partially withdrawn from the casing 1 has its upper end stretched over the mouth piece 5 until the upper edge of the inflation lies adjacent the flange 8 The mouth piece 5 is then pressed downwardly in the upper end of the casing 1 until the position shown in Figure Q is reached, or approximately thatl position.

The lower end of the inflation is then fitted over the nipple 3 and the locking ring Alscrewed into proper position. As clearly shown in the drawing, the flange 13 ts within the upper end of easing 1 in a manner to somewhat compress the interposed inflation so that it expands into the groove 7 The flange 9- is of such a diameter that when the inflation extends over the same, it will not pass within the casing l and the inflation is confined within the upper edge of the casing and the exterior surface of the flange. The result of this construction is that when the mouth piece is pressed downwardly within casing 1 the upper edge of the casing tends to move the exterior portion of the vention, we do not desire@ to limit ourselves to the same as various changes and modifications can be made4 in' the details of form and construction without departing from the invention as defined in the appended claims.

That we claim isz- I. In' al teat cup a tubular mouth piece having a pair of circumferential channels in its' periphery. p

2. In a teat cup a tubular mout-h piece having a pair of circumferential Ichannels in its periphery, and atapered wall extending downwardly from the lower channel.

p 3.' In a` teat cup a tubular mouth piece having apair of flanges of dierentl radii, the lower flange adapted to compress an inflationagainst the inner wall of an enclosing casing,` and the upper flange adapted to compress the inflation against the upper edge of' `the casing, and a groove above said flanges :l'or receiving the upper edge of the inflation;

4. In a teat cup1 the combination with a 4casing of substantially circular cross sec'- tion; and an inflation within the' same of a moutl'i' piece with-in the inflation,` having ai flange upon itspe'riph'ery, compressingthe inflation against the casing,a channel ab'ov'e the flange for receiving the inflation, a sec- Onld flange compressing the inflation against the'upfer-edge'v of the casing,f anda" groove above the second flange for receiving the edge of the' inflation. l

5. In' a teat' cup', a casing oft' substantially circular Y cross section, an nation within the casing, a mouthpiece--extending-within the inflation and:A having three substantially parallel outwardly extending circumferential flanges forming a pair of spaced circumferential channels, one of said flanges compressi-ng the inflation against the interior of the casing, another of said flanges compressing the inflation against the upper edge of the casing, and the third flange adapted to confine th'eupper'edge of. the in-V flat-ion in the upper channel.

6. In a. teat cup,` a casing, an` inflation within the casing, atubular mouthpiece' eX# tending within the inflation and1 having a pair of circumferentialsflanges, one of `said flanges compressing the inflation against the'interiorwall of thecasing, and theother flange compressing the inflationagainstI the upper edge of the casing'.

7. In a teat cup, 'a casing,y an inflation within the casing', a' tubular mouthpiece eX-` tending within the inflation `and having a pair of circumferential llang'esoneof said flanges compressing against the interior wal-l of the' (':asing5-tl1eA other flange vcoinpressing tlie inflation against the upper edge of the casing,. and a circumferential channel above' the lastnarncd flange adapted to receive and retain the upper edgeof the inflation'.

In* witness whereof wey have'.y hereuntoV set our hands this 19th day of February, 1920;
